I WINDOW SASH CONSTRUCTION Filed Sept. 21. 1932 INVNTOR FRED PIC/{EL WL/AM o/v 062615557 Patented July 17, 1934 v 1,966,992 WINDOWSASH CONSTRUCTION Fred Pickel and William von Poelgecst, ,Carlstadt,

Application SeptemberZl, 1932, :Serial No. 634,094 2 Claims. (o1. 20-46) The objects of this invention are to provide a window frame having double hung sliding windows which can readily-be cleanedfrom-the room side thereof. Said windows being adapted to be swung inwardly upon apivot.

Another important object is in the provision of a windowframe having only one weight for each window sash, thesashes-beingadapted to pivot adjacent one of the framestiles-the other stilebeing provided with aretractable inner bead andparting stripto permit swinging the sashes inwardly on the said pivot.

A still further object is in the provision of a window frame provided with a pivot for the inside sash, both sashes having means to detachably fasten them together so the outside face of the pane of the outside sash may be cleaned by swinging both sashes inwardly on the pivot for the inside sash.

Further objects and advantages of the invention will appear from the following disclosure thereof together with the attached drawing which illustrates a preferred form of embodiment thereof, and in which:

Fig. 1 is room side elevational view of a window frame constructed in accordance with this invention, a portion of one of the frame stiles being shown in sectional detail.

Fig. 2 is an enlarged, partially broken plan section showing details of the invention.

Fig. 3 is a further enlarged detail of the upper pivot member.

Fig. 4 is a similarly enlarged sectional detail of the lower retractable pivot pin and socket.

Fig. 5 is a fragmentary detail of a modified form of bead and parting strip retracting means.

The window frame comprises stiles and 11, the sill 12 and the upper rail 13. One of the stiles such as 10 may be entirely conventional in its structure, being divided into sash weight boxes 14 for the sash weights 15. It is provided in the usual manner with an inner bead 16 a parting strip 17 and an outer bead 18.

The other stile 11, has its upper portion conventionally constructed, but its lower portion, for a distance slightly in excess of the sash heights, is provided with a retractable inner stile board 19, having thereon an inner bead 20 and parting strip 21.

It is desirable that the board 19, when retracted, maintain a vertical position and to this end the inner portion of the stile 11 is provided with a vertically moving yoke 22 guided in slots of a framing member 23. Hinge elements, such as 24, are fastened to the inner face of the board and properly spaced for thebest results. Swinging portions 25 of the hinge elementsare pivotedto the yoke asindicated. A stop pin 26 is providedto abut a portionof theframing memally reached from the sash side of the stile to operate the board.

The detail shown in Fig. 5, illustrates ameans i rmam la m h rac ab eb rd 9 which 65 includes a knob handle 28 which may be turned to rotate an eccentric plate 29 engaged in the slotted plate 30 aiiixed to the top of the yoke 22. This arrangement permits manipulation of the board from the room side of the window stile. -70

To further assist in aligning the retractable board 19 with the fixed upper stile board there may be provided a stop plate 31 fixed with the upper board and adapted to be laterally abutted by the upper portion of the board 19.

The window sashes 32 and 33, respectively inner and outer, are adapted to slide in the usual manner and in the present invention are counterweighted on one side only by the sash weights 15. The inner window sash 32 is provided at the top and to one side, adjacent the stile 10, with a socket 34 adapted to receive a hinge pin 35 carried by the removable bracket 36. The bracket may be secured by means such as the screw 37 to a receiving plate 38 fixed to any portion of the stile 10.

In vertical alignment with the upper pin and socket, the inner sash may be provided at its lower portion with a retractable pin 39 adapted to engage in the socket 40 recessed in the window sill 12. The desirability for retracting the pin 39 will later be apparent and a simple means for accomplishing this is to provide a bore 41 in the sash 32 of suiificient depth to entirely conceal the pin. To maintain the pin in an extended position so as to engage the socket 40, a lateral projection 42 is arranged to engage the bayonet slot 43 of a ferrule 44 set into the bore 41.

The outer face of the inner sash is provided with spaced upwardly extending hooks 45 engageable with seats 46 in the bottom rail of the outer sash. The upper rail of the inner sash is preferably equipped with a latching hook 47 which is manipulated by the handle 43. The hook 4'7 is adapted to engage, either the stud 49 on the upper rail of the outer sash or the stud 50 on the lower rail thereof, as desired.

When the window is in normal use the bracket 36 is either removed or inverted so the pin 35 does not interfere with the sliding movement of 110.

by engaging the latching hook 47 with the stud 50.

The usual method for cleaning the inner face I of the sash panes may be followed and when it is desired to clean the outer face of the inner sash pane, the outer sash may be placed in any position provided its upper portion is retained in the slide grooves of both stiles of the frame.

The pin 39 is now extended with the projection 42 engaged in the horizontal portion of the bay.

onet slot 43 and the pin 39 seated in the socket 40, and with the bracket 36 attached so the pin seats in the socket 34, the inner sash frame is ready to be swung inwardly. This is readily accomplished by retracting the board 19 by raising the handle means 27 or turning the knob 28.

When it is desired to clean the outer face of the outer sash pane, this sash 33 is moved downwardly until the hooks 45 engage the seats 46, then the latch 47 may be coupled with the stud 49 and as the inner sash is swung inwardly, the outer sash will be carried by it.

When all the panes are clean, the parts may be restored to their normal position.

From the foregoing it will be seen that a simple device for the purpose has been disclosed in the preferred form of its embodiment, but it is not desired to restrict the details to the exact construction shown, it being obvious that changes,

not involving the exercise of invention, may be made without conflicting with the scope of the appended claims.

Having thus described our invention, what we claim as new and desire to secure by Letters Patent, is:

1. In a double hung sliding sash window frame having an inner sash andan outer sash, means topivot saidsashes comprising a single pin detachably secured to one frame stile and adapted to engage a socket in the upper portion of one of the sashes and a retractable pin carried in the lower portion of the same sash and engageablewith a socket in the sill of the window frame.

2. In a double hung sliding sash window frame, having an inner sash and an outer sash, means to pivot said sashes comprising a single pin, detachably secured to one frame stile and adapted to engage a socket in the upper portion of one of the sashes and a retractable pin carried in the lower portion of the same sash and engageable with a socket in the sill of the window frame, means to retract a portion of the sash retaining members of the other frame stile, comprising, a

vertically movable yoke, a board having a parting strip and inner bead thereon and spaced hinge members, connecting said yoke and board, whereby, when the yoke is moved vertically the board moves horizontally.
